Avoiding Lone "I" at End of Lines

Perhaps this has been answered a thousand times, but a google search retrieves nothing.
The problem is this.
In a long text document with flowing text (200 pages), with justification activated in paragraph composer, many of my lines end with the lone character "I". It is unsightly.
When the copy is fully ready, I can adjust the tracking line by line.
However, in the meantime, is there a global option somewhere that will tell ID to never, ever leave a stray "I" at the end of a line?
